Power-pop favorites The Posies currently are out on a 30th anniversary tour, and the band’s stop in St. Paul, Minn., on Tuesday night featured an extra treat: The group brought Hüsker Dü bassist Greg Norton onstage during the encore to rip through four of that band’s classics. See video of their performance right here.

Minnesota Public Radio’s The Current has just launched a five-part documentary podcast series called “Do You Remember?” that promises to trace the formative years and legacy of Hüsker Dü through interviews with those who were there as well as the three band members themselves — including Grant Hart.

Grant Hart, the founding drummer who served as co-songwriter/singer for pioneering hardcore-punk trio Hüsker Dü, a band that laced tuneful melody with blistering power to help define the ’80s indie scene, died overnight at the age of 56, the Minneapolis Star Tribune reports. He had been diagnosed with cancer.

After dropping hints for months, Numero Group today finally revealed full details of their multi-disc Hüsker Dü box set Savage Young Dü, which collects new remasters of the punk/hardcore trio’s entire studio output from 1979 to 1982 — including 47 unreleased tracks. See the full tracklist here.

The Hüsker Dü catalog famously has been in dire need of a sonic upgrade and expansion, and it seems, at long last, that it’s happening, courtesy of the Chicago-based reissue pros at the Numero Group, who are assembling something “massive” around the band’s archives.

This week’s new releases include new albums from Sinead O’Connor, Cocksure (Chris Connelly) and Stiff Little Fingers, box sets from John Foxx and Suzanne Vega and the documentary “Every Everything: The Music, Life and Times of Grant Hart.”

This week’s new releases include CD “vinyl replica” reissues from Midnight Oil and Iggy Pop, plus a first-time vinyl release of Grant Hart’s 1999 solo album ‘Good News for Modern Man’ and a live-in-the-studio set from Lone Justice recorded in 1983.

This week’s new releases include new studio albums from Hüsker Dü’s Grant Hart, Tears For Fears’ Curt Smith and The Teardrop Explodes’ Julian Cope, plus vinyl reissues from Cabaret Voltaire, The Birthday Party and Deacon Blue, a new remix collection from Section 25 and an Icehouse best-of.

Grant Hart returns this summer with his long-in-the-works The Argument, a double album based on John Milton’s epic “Paradise Lost,” on which Domino Record Co. says Hart “distills its essence into pop and rock concoctions that nimbly flit through the history of 20th century music.”

Gorman Bechard, director of the 2011 documentary “Color Me Obsessed: A Film About The Replacements,” is putting the finishing touches on a new film called “Every Everything” about former Hüsker Dü drummer, singer and songwriter Grant Hart — and he’s once again turning to fans for financial support for the project.

After making the rounds at film festivals and receiving art-house screenings over the past year, director Gorman Bechard’s documentary about The Replacements and their rabid fans — a film dubbed, appropriately, “Color Me Obsessed” — comes to DVD this fall in a two-disc set packed with six hours of extras.
